Expository essay (Does nuclear energy still have a part to play in the world?)

Nuclear energy is a form of an energy source just like natural gases, oil or petroleum. However, the nuclear energy plant has caused a nuclear crisis in Japan. Therefore, many people may now think that all the nuclear plants can only cause disasters. So, does nuclear energy still have a part to play in the world?


Firstly, what is nuclear energy? Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant, the fission process is used to generate heat for producing steam, which is used by a turbine to generate electricity. 


Nuclear energy is used to provide heat energy to run steam turbines for electricity to commercial and consumer users. It is also used in hospitals and medical practices for cancer therapy and diagnostic methods (MRI, PET, CAT, X-rays.) It is the fission material in nuclear bombs. It glows in dark electronics - especially older devices using radium. Nuclear energy is spent Uranium used in Artillery and other weapons. It is also used in lasing/massing/pump material in Lasers and Masers It provides power for space vehicles (rovers, orbiters). It is considered a raw material for high energy physics experiments nuclear-powered naval vessels use nuclear power to generate steam that is used for propulsion, water distillation and generating electricity.


Since nuclear energy has helped us in a lot aspects, it is also harmful, like how it has destroyed Japan. Nuclear energy still has a part to play since we need it or some things cannot be achieved like using nuclear energy for cancer therapy and diagnostics methods.
